Description
Technical Field
[0001] This utility model belongs to the field of insulator manufacturing technology, and in particular relates to a top grooving device for the production of column insulators. Background Technology
[0002] Post-type insulators are electrical devices used in power systems, providing both mechanical support and electrical insulation. They are widely used in substations to support busbars, disconnectors, circuit breakers, etc.; they are also used for structural insulation of 35kV and above transmission lines, such as transformer bushings and switchyard supports. They are also used in special areas such as high altitudes and heavily polluted areas. The main body of a post-type insulator is cylindrical or elongated, typically made of ceramic, glass, or composite materials. Its top and bottom are fitted with cast iron or steel flanges and other metal fittings for fixing and connecting equipment or supports. The insulator surface is usually corrugated to increase creepage distance, prevent arc flashover, and each corrugation also helps to block arcing and sewage flow, preventing uneven adhesion of pollutants and improving its anti-pollution capability.
[0003] To accommodate mechanical assembly requirements, grooves are milled into the top or bottom of insulators or at connections with other equipment to achieve precise assembly. "Positioning grooves" or "bolt grooves" are milled into the flange surface to ensure accurate connection between the insulator and the support or equipment, preventing stress concentration caused by installation deviations. In some scenarios, grooves are milled at the junction of the flange and the insulator body to embed sealing strips or anti-loosening gaskets, improving overall sealing and enhancing the stability of the mechanical connection.
[0004] However, due to the special structure of insulators, the surface of insulators is usually made into a corrugated shape, which makes it difficult to position them during the milling process. Therefore, a suitable tooling fixture is needed to clamp and position the insulators during milling. Utility Model Content
[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a top grooving device for the production of column insulators, which achieves the function of fixing the insulators and is simple and reliable to operate.
[0006] In view of this, the present invention provides a top grooving device for the production of column insulators, including a milling machine, wherein the milling machine is provided with a positioning fixture, the positioning fixture including a fixture base, and the fixture base is provided with: The first V-shaped member is used to support the cylindrical section of the column insulator below; The second V-shaped member is used to support the bottom of another cylindrical section of the column insulator; The first V-shaped member and the second V-shaped member are spaced at least by one corrugated section. The first V-shaped member is fixedly installed, and the second V-shaped member can be moved closer to or further away from the first V-shaped member through a position adjustment structure. The ends of the first V-shaped member and the second V-shaped member are attached to the ends of the corrugated section to limit the insulator in the length direction of the insulator.
[0007] In this technical solution, by placing the two cylindrical segments of the post insulator on the first V-shaped member and the second V-shaped member, the insulator can be positioned circumferentially. At the same time, the first V-shaped member is fixed, and the end of one corrugated segment is attached to the end of the first V-shaped member. Then, the position of the other second V-shaped member is adjusted to be close to or away from the first V-shaped member so that the second V-shaped member is attached to the other end of the same corrugated segment or the end of another corrugated segment. This can restrict the displacement of the insulator in the length direction, thereby fixing the insulator. The operation is simple and reliable.
[0008] Furthermore, the position adjustment structure includes: An adjusting screw is provided along the length of the column insulator, and both ends of the adjusting screw are rotatably connected to the fixture base. A second V-shaped member is slidably disposed on the fixture base along the length of the column insulator and is screwed to the adjusting screw.
[0009] In this technical solution, the second V-shaped component can slide linearly on the adjusting screw by rotating the adjusting screw.
[0010] Furthermore, an adjustment knob is connected to the end of the adjusting screw away from the first V-shaped member.
[0011] Furthermore, the ends of the first V-shaped member and the second V-shaped member are provided with extension blocks, and the distance from the extension blocks to the outer diameter of the insulator is greater than the distance from the lowest point of the V-shaped part to the outer diameter of the insulator.
[0012] In this technical solution, because a transition arc is provided between the cylindrical segment and the corrugated segment, and an extension block is set at a lower position, the transition arc can be avoided from touching the end of the corrugated segment, thus ensuring accurate positioning and firm clamping.
[0013] Furthermore, the first V-shaped member and the second V-shaped member are located on both sides of the same corrugated segment of the insulator.
[0014] Furthermore, the first V-shaped member is slidably mounted on the fixture base and can slide along the length direction of the column insulator. The first V-shaped member and the fixture base are fixedly connected by a locking structure.
[0015] In this technical solution, the first V-shaped component can slide along the length of the column insulator. The position of the first V-shaped component can be adjusted according to the insulator with different specifications and structures, so that the first V-shaped component can be positioned in a suitable position and supported under the appropriate column section of the insulator. After adjustment, the position of the first V-shaped component is fixed by a locking structure, so that the first V-shaped component is fixed in the tooling seat, which can improve the versatility of the tooling.
[0016] Furthermore, the tooling base includes a base and an L-shaped support rod disposed on the base. The L-shaped support rod includes a long rod section and a short rod section. The first V-shaped member and the second V-shaped member are both slidably disposed on the long rod section. The adjusting screw passes through the short rod section parallel to the long rod section and is rotatably connected to the short rod section.
[0017] Furthermore, an extension plate extends from the middle of the long rod section, parallel to the short rod section, and the adjusting screw is connected to the short rod section and the extension plate in a transmission connection.
[0018] In this technical solution, the support at both ends can make the adjusting screw more stable.
[0019] Furthermore, the locking structure includes: A sliding groove is formed on the long rod section; A connecting hole is formed on the first V-shaped member; A locking bolt, which extends from one side of the first V-shaped member through a connecting hole and a sliding groove to the other side of the first V-shaped member; A locking nut, which is connected to a locking bolt threaded connection for locking the first V-shaped member onto the long rod section.
[0020] Furthermore, the V-shaped angle of both the first V-shaped member and the second V-shaped member is 120°.
[0021] The beneficial effects of this utility model are: 1. By placing the two cylindrical segments of the post insulator on the first V-shaped member and the second V-shaped member, the insulator can be positioned circumferentially. At the same time, the first V-shaped member is fixed, and the end of one corrugated segment is attached to the end of the first V-shaped member. Then, the position of the other second V-shaped member is adjusted to be close to or away from the first V-shaped member so that the second V-shaped member is attached to the other end of the same corrugated segment or the end of another corrugated segment. This can restrict the displacement of the insulator in the length direction, thereby fixing the insulator. The operation is simple and reliable.
[0022] 2. Because a transition arc is provided between the cylindrical section and the corrugated section, the extension block, which is positioned at a lower position, can avoid the transition arc from touching the end of the corrugated section, thus ensuring accurate positioning and firm clamping.
[0023] 3. The first V-shaped component can slide along the length of the column insulator. The position of the first V-shaped component can be adjusted according to the insulator of different specifications and structures, so that the first V-shaped component can be positioned in a suitable position and supported under the appropriate column section of the insulator. After adjustment, the position of the first V-shaped component is fixed by the locking structure, so that the first V-shaped component is fixed in the tooling seat, which can improve the versatility of the tooling.

[0031] Example 1 like Figure 1-4 As shown, a top grooving device for producing a column-type insulator 2 includes a milling machine 17, on which a positioning fixture 18 is provided. The positioning fixture 18 includes a fixture base 7, on which the following are provided: The first V-shaped member 1 is used to support the cylindrical section 3 of the column insulator 2 below; The second V-shaped member 4 is used to support the other cylindrical segment 3 of the column insulator 2 below; The first V-shaped member 1 and the second V-shaped member 4 are spaced apart by at least one corrugated segment 5. The first V-shaped member 1 is fixedly installed, and the second V-shaped member 4 can be moved closer to or further away from the first V-shaped member 1 through a position adjustment structure. The ends of the first V-shaped member 1 and the second V-shaped member 4 are attached to the side ends of the corrugated segment 5 to limit the insulator 2 in the length direction of the insulator 2.
[0032] By placing the two cylindrical segments 3 of the post insulator 2 on the first V-shaped member 1 and the second V-shaped member 4, the insulator 2 can be positioned in the circumferential direction. At the same time, the first V-shaped member 1 is fixed, and the end of one corrugated segment 5 is attached to the end of the first V-shaped member 1. Then, the position of the other second V-shaped member 4 is adjusted to be close to or away from the first V-shaped member 1 so that the second V-shaped member 4 is attached to the other end of the same corrugated segment 5 or the end of another corrugated segment 5. This can restrict the displacement of the insulator 2 in the length direction, thereby fixing the insulator 2. The operation is simple and reliable.
[0033] Example 2 like Figure 1-4 As shown, the position adjustment structure includes: An adjusting screw 6 is provided, which is positioned along the length of the column insulator 2 and is rotatably connected to a fixture base 7 at both ends. A second V-shaped member 4 is slidably mounted on the fixture base 7 along the length of the column insulator 2 and is screwed onto the adjusting screw 6. Rotating the adjusting screw 6 allows the second V-shaped member 4 to slide linearly along it. An adjusting knob is connected to the end of the adjusting screw 6 furthest from the first V-shaped member 1.
[0034] The ends of the first V-shaped member 1 and the second V-shaped member 4 are provided with extension blocks 8. The distance from the extension block 8 to the outer diameter of the insulator 2 is greater than the distance from the lowest point of the V-shaped part to the outer diameter of the insulator 2. Since the cylindrical section 3 and the corrugated section 5 are connected by a transition arc 9, the extension block 8, which is positioned lower, can avoid the transition arc 9 from contacting the end of the corrugated section 5, thus ensuring accurate positioning and firm clamping.
[0035] The first V-shaped member 1 and the second V-shaped member 4 are located on both sides of the same corrugated segment 5 of the insulator 2.
[0036] Example 3 like Figure 1-4As shown, the first V-shaped component 1 is slidably mounted on the fixture base 7 and can slide along the length of the column insulator 2. The first V-shaped component 1 and the fixture base 7 are fixedly connected by a locking structure. The first V-shaped component 1 can slide along the length of the column insulator 2, and its position can be adjusted according to the different specifications and structures of the insulator 2, so that the first V-shaped component 1 can be positioned in a suitable position and supported under the appropriate column section 3 of the insulator 2. After adjustment, the position of the first V-shaped component 1 is fixed by the locking structure, so that the first V-shaped component 1 is fixed on the fixture base 7, which can improve the versatility of the fixture.
[0037] The tooling base 7 includes a base 10 and an L-shaped support rod 11 disposed on the base 10. The L-shaped support rod 11 includes a long rod section 12 and a short rod section 13. The first V-shaped member 1 and the second V-shaped member 4 are both slidably disposed on the long rod section 12. The adjusting screw 6 passes through the short rod section 13 parallel to the long rod section 12 and is rotatably connected to the short rod section 13.
[0038] An extension plate 14, parallel to the short rod section 13, extends from the middle of the long rod section 12. The adjusting screw 6 is connected to the short rod section 13 and the extension plate 14. Supports at both ends make the adjusting screw 6 more stable.
[0039] The locking structure includes: Sliding groove 15, the sliding groove 15 is formed on the long rod section 12; A connecting hole is formed on the first V-shaped member 1; Locking bolt 16, which extends from one side of the first V-shaped member 1 through the connecting hole and the sliding groove 15 to the other side of the first V-shaped member 1; A locking nut, which is threaded onto the locking bolt 16, is used to lock the first V-shaped member 1 onto the long rod section 12.
[0040] The V-shaped angle of the first V-shaped member 1 and the second V-shaped member 4 is 120°.
[0041] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
